Expand 450 Gb LUN (Raid 5) to 550 Gb in VNX 5300

I want to expand 450 Gb LUN (Raid 5) to 550 Gb in VNX 5300. Ihave created 100Gb LUN with same raid 5, while expanding am unable to see created 100 Gb lun in striping option, i.e. created 100 Gb lUN is able to access through Concatenation. Can anyone suggest me what I have to choose?

First of all check 450 gb lun is meta lun or single hyper lun. If it is meta
lun then check hyper size. Expanding meta in stripe will require same size
hypers as existing. If it is single hyper lun, then you need to create
another 450 gb hyper to stripe lun. If you want it to make size of 550 gb
then go with concate option.

Is it is very much helpful to me and thanks for your help, but i want add 100 gb same configured Raid 5 lun to single slice 400 Gb raid 5 lun in Striping...is it possible...? am dint getting created 100 gb lun in striping ,,,where as am able to get same created lun in concatenation...

What you want is not posible, either add a same size slice to be able to stripe (400gb) or create a new meta the size you need (ie 4x 125 or 2x250) and then use lun migrator, this within the VNX, is non disruptive

Although this is a task that can be performed, I do not recommend doing this. You may not see the immediate performance impacts, however over time you will start to see performance degrade. Once this occurs, you may ultimately need to audit your layout and possible redo it.

Again, this may give you short term gains. If not monitored, corrected you will have long term performance problems.
